ChatGPT joue au docteur avec 230M de personnes chaque semaine !

The intersection of artificial intelligence and healthcare is no longer a futuristic concept; it is a massive, present-day reality. Every week, 230 million people turn to ChatGPT with health-related questions. This staggering figure highlights a profound shift: in many regions, particularly the United States, the healthcare system is so fragmented and expensive that consulting an AI has become simpler and more accessible than seeing a doctor. This discussion, hosted by Carlos Diaz with guests Clément Pouget-Osmont, Arnaud Moulet-Berto, and Valran, explores how the tech giants are invading the world’s largest market and what this means for the future of the human body. ### The Rise of the AI Health Assistant The launch of "GPT Health" by OpenAI marks a significant turning point. This dedicated space allows users to connect their medical records and health applications directly to the AI. The goal is to reach the "Graal" of medical AI: a system that possesses full context, including family history, genomic data, blood tests, and even environmental factors. A compelling anecdote shared during the talk involved Fidji Simo, CEO of Instacart and a former Facebook executive, who used ChatGPT at the emergency room to cross-reference a doctor's prescription with her complex medical history. The AI identified a contraindication that the human doctor had missed, potentially preventing a serious medical error. While the US legal framework often shifts responsibility to the patient once they consent to share data, Europe faces a slower rollout due to the AI Act and GDPR, which treat health data as a "very high risk" category. In France, specifically, citizens do not even have the right to access their own genomic data, creating a barrier to the kind of "sovereign individuality" AI could offer. ### Reliability versus Accessibility Despite concerns about reliability—illustrated by an anecdote where ChatGPT mistakenly suggested a stroke for a minor bruise—the speed and availability of AI are winning over the public. ChatGPT has effectively become the most used health application in the world, surpassing dedicated medical platforms because it meets an immediate need for information, especially when human doctors are unavailable or rushed. The medical profession itself is being reshaped. Startups like Nabla are already using AI to handle administrative tasks, allowing doctors to focus on the patient rather than their screens. However, two diverging paths for the future of medicine emerge: one where doctors become mere "stamps" for AI-generated prescriptions, and a more optimistic one where doctors use AI-provided data to transition into high-level preventive and functional medicine. ### The $10 Trillion Market Healthcare represents 18% of the US GDP and is the third-largest sector globally. While tech giants like Google and Amazon have seen high-profile failures in this space (such as the closure of Haven), they are now finding success in specific niches. Microsoft earns billions through cloud services for health, and Amazon is expanding via its One Medical clinics. The financial opportunity lies in three pillars: 1. **Clinical Care:** Optimizing clinics to run with fewer staff through automation. 2. **Pharma and Biotech:** Using AI to accelerate drug discovery, as seen with companies like Insilico Medicine, which uses AI to find new protein candidates for treatments. 3. **Insurance:** AI that knows a user’s habits and biology perfectly is uniquely positioned to price and provide health insurance, potentially disrupting traditional models. ### The Longevity Obsession There is a growing cross-generational obsession with longevity, particularly among Gen Z and Millennials. Surprisingly, 42% of younger Americans express a desire to live "forever." This trend is driven by three factors: the post-COVID realization of physical vulnerability, a desire to regain control in an anxious world (climate change, war, AI job displacement), and a natural comfort with health-tracking wearables. For the younger generation, longevity is a strategy for "agency." In an economy where traditional milestones like home ownership and career stability are delayed, having "more time" is seen as a necessary resource to eventually succeed. This has led to a "bio-hacking" culture where young people are consuming significantly less alcohol and investing heavily in their "healthspan." ### Mental Health and Digital Empathy The crisis in mental health is equally significant. With nearly 45% of young adults reporting anxiety or depression, many are using ChatGPT as a surrogate therapist. Users report feeling "less judged" and "not rushed" when talking to the AI. While AI cannot replace the biological "shared experience" or the serotonin release of human touch, its 24/7 availability makes it an unbeatable tool for crisis management and trauma processing. ### The New Frontier of Sensors The next generation of medical technology moves beyond simple step-counting. New devices are becoming "invisible" and highly specialized: * **Brain-Wave Sensors:** Devices like "Aware" fit behind the ear to measure mental clarity and focus, acting as a "pacemaker for the brain" and potentially detecting neurodegenerative diseases early. * **Neurostimulation:** Discoveries regarding 40Hz light and sound frequencies are being used to stimulate gamma waves, showing promise in fighting Alzheimer’s. * **Camera-Based Biometrics:** Technology like Anura can measure heart rate, stress, and even blood glucose levels through a simple 30-second video selfie, eliminating the need for physical contact. * **Smart Glasses:** Meta and others are developing glasses that can passively track caloric intake and provide real-time nutritional advice by simply looking at a restaurant menu. ### Conclusion: A French Influence The discussion concludes on a note of "French pride." Many of the key figures leading this AI health revolution—including Yann LeCun, Alexandre Lebrun, and Fidji Simo—are French. With the success of platforms like Doctolib, France has shown a readiness to adopt digital health solutions. The future of healthcare lies in this delicate balance between hyper-technological tracking and the essential need for human connection, as seen in the development of "transparent" tech for seniors that allows them to stay in their homes longer while being monitored by AI.
